Objective To investigate the effect of Notch1 and Jagged1 on the growth of prostate cancer PC3 cells and the regulation of Jagged1 expression by its receptor Notch1 in PC3. Methods Notch1 and Jagged1 expression were inhibited by siRNA interference. The growth rate of PC3 cells was measured by MTT. Notch1 expression was inhibited by siRNA interference and promoted by transfection of Notch1 cDNA. The changes of Notch1 and Jagged1 protein and mRNA levels were measured by Western blot and Real-time RCR. Results The growth of PC3 cells decreased after inhibiting Notch1 and Jagged1 expression. Jagged1 protein level decreased after inhibiting Notch1 expression and increased after over-expressing Notch1. Moreover, the change of Jagged1 protein level was discordant with the situation of mRNA. Conclusion In PC3 cells, Notch1 and Jagged1 are important to cell growth. Notch1 may regulate Jagged1 expression.

Objective To compare the effect of GammaTM wet wipes and 75% alcohol on the disinfection of X-ray protective clothing,and provide reference for choosing rational disinfection methods.Methods 62 pieces of X-ray protective clothing were selected,30 were from operating rooms,32 from catheterization room.Protective clothing were randomly divided into trial group and control group,each had 31 pieces.Trial group disinfected clothing with GammaTM wet wipes,control group disinfected clothing with 75% alcohol,disinfection effect,drying time,and cost between both groups were compared.Results Average bacterial colony counts in trial group and control group before disinfection were 2.38 CFU/cm2 and 2.36 CFU/cm2 respectively,qualified rates were 80.64% and 83.87%respectively.Bacteria were not detected in both groups after disinfection.The average drying time in trial group was shorter than control group([352.35±9.93]s vs[676.13±10.62]s,t=123.98,P <0.01).The cost of disinfecting X-ray protective clothing in trial group was 29.60% less than control group.Conclusion Effect of GammaTM wet wipes and 75% alcohol on disinfecting X-ray protective clothing are both reliable,compared with 75% alcohol, GammaTM wet wipes are without corrosion,have shorter drying time,and save more cost.

The left ventricular function of 103 normal subjects in the age range of 17 to 48 were examined with three echocardiographic methods, the Pombo's method (Method I), Fortuin's method (Method II) and Lalani's method (Method III), in order to evaluate their relative efficiency. The results were as following:( 1 ) The value of left ventricular end diastolic volume determined with Method II was larger than that determined with Method 1(123. 9?22.6vsl05. 43?26.0 ml, P0. 05).( 2 ) The values of stroke volume, stroke index, cardiac output, and cardiac index were the largest as determined with Method II, the second with Method I and the smallest with Method III. For instance, the value of cardiac index was 4.66 ?1.21 /m2/min wita Method 11,3.81?1.0 with Method I, and 2.96?0.8 with Method III(P0. 05).( 4 ) All the parameters obtained from Methods I and II were correlated with each other closely (r = 0.72 - 0.96, P0.05).( 5 ) Methods I and II are simple to operate and easy to reproduce and there have been a lot of parameters obtained with these two methodds. However the systolic mitral closure slope of Method III is rather difficult to determine and the parameters obtained with Method III are comparatively less in number.It is concluded that Methods I and I of the echocardiographic technique are the methods of choice in determining the left ventricular function of a normals-sized or nearly normal-sized heart since they are simple, effective and accurate.

BACKGROUND: Glutamine (Gln) supplementation is known to decrease oxidative stress and inflammatory response, enhance resistance to infectious pathogens, shorten hospital stay, and decrease medical costs of patients. This study was undertaken to evaluate the relationship between the effect of early parenteral glutamine (Gln) supplement on acute liver injury (ALI) and heat shock protein 70 (HSP-70) expression in critical patients. METHODS: Forty-four patients who had been admitted to the emergency intensive care unit (EICU) of Nanjing First Hospital Affiliated to Nanjing Medical University were randomly divided into a control group (n=22) and a Gln group (n=22). The patients of the two groups received enteral and parenteral nutrition. In addition, parenteral Gln 0.4 g/kg per day was given for 7 days in the Gln group. Serum HSP-70 and Gln were measured at admission and at 7 days after admission. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBiL), serum levels of HSP-70 and Gln, mechanical ventilation (MV) time, ICU stay, peripheral blood of TNF-α, IL-6, CD3, CD4 and CD4/CD8 levels were also measured in the two groups. RESULTS: In the Gln group, the levels of serum HSP-70 and Gln were significantly higher after Gln treatment than those before the treatment (P<0.01). HSP-70 level was positively correlated with the Gln level in the Gln group after administration of parenteral Gln (P<0.01). The levels of serum ALT, AST, TBiL and TNF-α, IL-6 were lower in the Gln group than in the non-Gln group (P<0.01). MV time and ICU stay were significantly different between the two groups (P<0.05). The levels of CD3, CD4 and CD4/CD8 were significantly higher in the Gln group than in the control group after treatment (P<0.05). CONCLUSION: Parenteral Gln significantly increases the level of serum HSP70 in critically ill patients. The enhanced expression of HSP70 is correlated with improved outcomes of Gln-treated patients with acute liver injury.

Objective To observe the therapeutic efficacy of needling QIN's eight head acupoints in treating insomnia.Method Sixty patients were randomized into QIN's eight head acupoints group (30 cases) and a conventional acupuncture group (30 cases). The modified Spiegel sleep questionnaire was evaluated respectively after 4-week and 8-week treatment.Result After 4-week treatment, there was a significant difference in comparing the modified Spiegel sleep questionnaire between the two groups (P<0.05), and QIN's eight head acupoints group was superior to the conventional acupuncture group; after 8-week treatment, there was no significant difference between the two groups in comparing the modified Spiegel sleep questionnaire (P>0.05).Conclusion QIN's eight head acupoints group had a more significant therapeutic efficacy compared to conventional acupuncture group after 4-week treatment.

Objective To investigate the application value of transcranial Doppler ultrasonography(TCD) in critically ill children with cerebral dysfunction.Methods We detected the cerebral blood flow parameters[systolic velocity(Vs),mean velocity(Vm),end of diastolic velocity(Vd),pulsatility index(PI),resistance index(RI)] of middle cerebral artery in cerebral dysfunction group(n=20) and control group(no cerebral dysfunction,n=20),and observed the differences of those parameters between two groups.Children in cerebral dysfunction group were also divided into groups according to Glasgow Coma Score(GCS) and prognosis.The differences of each TCD parameter in diverse groups divided by GCS and by prognosis were analysed.Children in cerebral dysfunction group were checked TCD everyday until TCD parameters were normal.The relation between the days of TCD parameters′ reaching normal and GCS,duration of disorder of consciousness with correlation analysis were analysed.Results Vs,PI,RI in cerebral dysfunction group were higher than those in control group,while Vd was lower (P<0.05).(2)PI in the group of GCS less than 6 points(0.91±0.21) was higher than that in group of GCS 7-13 points(0.83±0.14)(P<0.05).The other parameters between two groups of GCS less than 6 points and GCS 7-13 points were not significantly indistinctive.Between the good prognosis group and the bad prognosis group,there were no significant differences in all parameters.(3) The days of TCD parameters′ reaching normal were negatively correlated with GCS(r=-0.653,P<0.01),but positively correlated with the duration of disorder of consciousness(r=0.923,P<0.01).Conclusion The cerebral hemodynamics of children with cerebral dysfunction is abnormal,the more serious cerebral dysfunction,the higher PI and the longer time for regaining normal TCD parameters.Constantly monitoring TCD could reflect the changes of cerebral hemodynamics and is valuable to assess the state of illness and prognosis.
